Patent attributes
This invention relates to locking devices and particularly to an actuator assembly for a locking device with electronic control. The actuator assembly includes: a motor, having a drive shaft installed to a motor shaft, and a coil spring installed to the drive shaft, and further includes: a follower shaft capable of displacing in an axial direction in the coil spring, and a pin installed onto the follower shaft and rotatable into the coil spring, and the follower shaft is extended into the coil spring and slidably fitted to the coil spring. Compared with the prior art, this invention effectively maintains a radial limitation of the cylinder spring to overcome the vibration of the spring occurred during the rotation of the cylinder spring and the axial displacement of the follower shaft.
